code coverage tool with emacs integration?

[John J. Lee]

Anybody know of one?

Actually, I have a feeling that emacs understands a standard format
for errors, which would make it really easy to implement this by
having the coverage tool print results in that format -- anybody know
where to find the details?


I also wonder if some kind of graphical display might be useful
somehow, having been inspired by this:

(really, I just like the pretty pictures :)
